IPC: H01B7/14
Filed: 1930-02-12
Abstract: 345,428. Submarine cables. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Feb. 12, 1930, No. 4761. Convention date, May 10, 1929. [Class 36.] In order to reduce the diameter of a four-core submarine cable, the conductors are formed with quadrantal cross-sections. In the construction shown, a submarine cable comprises quadrantal-shaped conductors s insulated with paper or the like i and surrounded by lead sheaths b<1>, b<2>, between which is arranged a pressureprotecting covering d of shaped wires. A steel wire armouring a embedded in a serving of impregnated jute or the like j completes the cable. The quadrantal-shaped conductors, which are preferably formed by conjointly drawing several circular or pre-shaped wires as shown in Figs. 3 and 4, may have slightly rounded edges to prevent damage to the insulation. Specification 22923/92, [Class 36, Electricity, Conducting &c.], is referred to.

Title: Liquefaction and revaporization of gases
IPC: F17C9/04
Filed: 1966-02-03
Abstract: 1,084,622. Liquefaction and re-vaporization of natural gas. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Feb. 3, 1966 [Feb. 5, 1965], No. 4809/66. Heading F4P. Liquefaction of natural hydrocarbon gas or revaporization of the gas in the liquid phase is effected by indirect heat exchange with a cold carrier comprising water mixed with at least one freezing point depressant; the carrier thus being warmed when effecting liquefaction and cooled during revaporization of the natural gas. Suitable depressants include ammonia, alcohols and diethylene glycol. After revaporization of liquid methane transported by tanker the socooled cold-carrier is fed into the tanker reservoir, transported back to the supply port and used to liquefy natural gas being loaded into the tanker. The so-warmed cold-carrier may either be transported back to the unloading port or the depressant, e.g. ammonia, removed therefrom and used in the manufacture of fertilizer or taken back to the unloading port.

Title: Improvements relating to underfeed stokers
IPC: F23K3/12
Filed: 1922-02-20
Abstract: 175,977. Ratel, M. Feb. 25, 1921, [Convention date]. Mechanical stoking; grates; ash-pits.-In an underfeed stoker adapted to be applied to locomotive boiler furnaces, as shown in Fig. 1, marine boiler furnaces, as shown in Fig. 4, or other furnaces, fuel is fed by reciprocating rams 3 from a hopper or hoppers 4 into longitudinal troughs 1 arranged between tuyeres 2 of decreasing height towards the centre of the grate, as shown in Fig. 2, so as to form a trough-shape fuel-supporting surface. The rams 3 may be driven by any suitable means and may have the same length of stroke or strokes decreasing in length towards the centre of the grate. In the arrangement shown in Fig. 1, the rams are driven from the pistons of steam cylinders connected to a pivoted crossbar which is connected to the rods 10 of the rams 3 in such a manner that the stroke of each ram may be varied. Secondary feeding devices 5 are mounted on rods 6 at the bottom of each trough and receive reciprocating motion similar to or different from the rams 3. The combustion of the fuel is completed on grates 12 and the ashes and clinkers are discharged by rotary crushers 13. In the arrangement shown in Fig. 4, the rams are driven from a crank-shaft 33 through connecting-rods 35 which also transmit movement to the clinker crushers 13 and pushers 41 for removing ashes. The tuyeres comprise corrugated bars 44, Fig. 6, mounted in dovetail slots formed in removable end plates 46. Air inlets 49 are provided between the plates 44 and they may be of tapering form. Fig. 10 shows a modified form of tuyeres consisting of water-tubes 55 which may be connected to the water spaces of the boiler or to a tank. Blast may be supplied to the tuyeres by a fan or the like, or in the case of locomotives it may be supplied by the motion of the locornotive or by means of steam jets arranged in the blast conduit. According to the Specification as open to inspection under Sect. 91 (3) (a), the mechanism for operating the rams 3, Fig. 1, is connected by a series of links and levers to rams 20 and pushers 21 for feeding fuel from the locomotive tender along troughs 19 to the hoppers 4. The hoppers are provided with plates 31 which are connected to the troughs 19 by articulated plates 32. Arching of the fuel in the tender above the discharge outlets is prevented by reciprocating rods 30. To prevent damage to the stoker in the event of foreign matter in the fuel stopping the movement of the feeding ram 3, the connecting-rod driving the ram is made in two parts and comprises a rod 58, Fig. 11, (Cancelled), having an enlargement 63 adapted to slide in a sleeve 57. The forward thrust of the rod 58 is transmitted to the ram through levers pivoted at 60 and held against the rod 58 by springs 61 which allow the levers to yield in the event of the ram becoming jammed. This subject-matter does not appear in the Specification as accepted.

Abstract: 840,862. Glass fibre manufacture. MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE SAINT-GOBAIN, CHAUNY & CIREY S. A., DES. Feb. 18, 1958 [March 12, 1957], No. 5205/58. Class 56. In a process for the manufacture of glass fibres, in which molten material, contained in a rotating hollow body equipped with a row or rows of apertures on its periphery, is projected through the apertures by centrifugal force, a gaseous current is caused to act on the streamlets leaving the body 1 in an enclosed annular zone associated with the peripheral band 2 of the body, the arrangement of the zone being such that the current has a substantially homogeneous temperature and a substantially equal velocity throughout the whole of the zone. As shown in Fig. 1, the flow of high temperature and high speed gas comes from a combustion chamber 4 having a continuous slot 4a concentric with the centrifuging body 1 through which the gas escapes and is canalised into a conduit formed of an inclined part 5a, 6 and a cylindrical part 5b. In a modification, Fig. 2 (not shown), a winding is provided for heating the band 2 by induction. In another modification, Fig. 3 (not shown), there is provided a canal with constant horizontal crosssection adjoining the divergent canal 7 and above the annular canal 8 opposite the band 2. A heating winding is also incorporated. In a modification, Fig. 4 (not shown), the canal 10 of Fig. 3 is eliminated and a canal having increasing horizontal cross-section is formed after the annular canal 8. In another modification shown in Fig. 5 the gas is mixed with air arriving laterally at 15 and passes into a canal 18 with decreasing horizontal crosssection, and then into a canal 19 with increasing horizontal cross-section, followed by a canal of constant horizontal cross-section 20 covering the whole height of the peripheral band 2 and a part of the conduit situated upstream. Finally there is provided a canal 22 of increasing horizontal cross-section at the outlet from the canal 20. Specification 840,863 is referred to.
